VM_METHOD_TYPE_REFINED to the class refined by the refinement if
the target module is a refinement. When a method entry with
VM_METHOD_TYPE_UNDEF is invoked by vm_call_method(), a method with
the same name is searched in refinements. If such a method is
found, the method is invoked. Otherwise, the original method in
the refined class (rb_method_definition_t::body.orig_def) is
invoked. This change is made to simplify the normal method lookup
and to improve the performance of normal method calls.
* vm_method.c (EXPR1, search_method, rb_method_entry),
vm_eval.c (rb_call0, rb_search_method_entry): do not use
refinements for method lookup.
* vm_insnhelper.c (vm_call_method): search methods in refinements if
ci->me is VM_METHOD_TYPE_REFINED. If the method is called by
super (i.e., ci->call == vm_call_super_method), skip the same
method entry as the current method to avoid infinite call of the
same method.
* class.c (include_modules_at): add a refined method entry for each
method defined in a module included in a refinement.
* class.c (rb_prepend_module): set an empty table to
RCLASS_M_TBL(klass) to add refined method entries, because
refinements should have priority over prepended modules.
* proc.c (mnew): use rb_method_entry_with_refinements() to get
a refined method.
* test/ruby/test_refinement.rb (test_inline_method_cache): do not skip
the test because it should pass successfully.
* test/ruby/test_refinement.rb (test_redefine_refined_method): new
test for the case a refined method is redefined.

add a new otpimization and its macro `OPT_CALL_CFUNC_WITHOUT_FRAME'.
This optimization makes all cfunc method calls `frameless', which
is fster than ordinal cfunc method call.
If `frame' is needed (for example, it calls another method with
`rb_funcall()'), then build a frame. In other words, this
optimization delays frame building.
However, to delay the frame building, we need additional overheads:
(1) Store the last call information.
(2) Check the delayed frame buidling before the frame is needed.
(3) Overhead to build a delayed frame.
rb_thread_t::passed_ci is storage of delayed cfunc call information.
(1) is lightweight because it is only 1 assignment to `passed_ci'.
To achieve (2), we modify GET_THREAD() to check `passed_ci' every
time. It causes 10% overhead on my envrionment.
This optimization only works for cfunc methods which do not need
their `frame'.
After evaluation on my environment, this optimization does not
effective every time. Because of this evaluation results, this
optimization is disabled at default.
* vm_insnhelper.c, vm.c: add VM_PROFILE* macros to measure behaviour

These information are stored in rb_call_info_t at the compile

This technique simplifies parameter passings at related
function calls (~10% speedups for simple mehtod invocation at

th->base_block is information for (a) parsing, (b) compiling
and (c) setting up the frame to execute the program passed by
`eval' method. For example, (1) parser need to know up-level
variables to detect it is variable or method without paren.
Befor (a), (b) and (c), VM set th->base_block by passed bindng
(or previous frame information). After execute (a), (b) and (c),
VM should clear th->base_block. However, if (a), (b) or (c)
raises an exception, then th->base_block is not cleared.
Problem is that the uncleared value th->balo_block is used for
irrelevant iseq compilation. It causes SEGV or critical error.
I tried to solve this problem: to clear them before exception,
but finally I found out that it is difficult to do it (Ruby
program can be run in many places).
Because of this background, I set th->base_block before
compiling iseq and restore it after compiling.
Basically, th->base_block is dirty hack (similar to global
variable) and this patch is also dirty.

Before this commit:
`finish frame' was place holder which indicates that VM loop
needs to return function.
If a C method calls a Ruby methods (a method written by Ruby),
then VM loop will be (re-)invoked. When the Ruby method returns,
then also VM loop should be escaped. `finish frame' has only
one instruction `finish', which returns VM loop function.
VM loop function executes `finish' instruction, then VM loop
function returns itself.
With such mechanism, `leave' instruction (which returns one
frame from current scope) doesn't need to check that this `leave'
should also return from VM loop function.
Strictly, one branch can be removed from `leave' instructon.
Consideration:
However, pushing the `finish frame' needs costs because
it needs several memory accesses. The number of pushing
`finish frame' is greater than I had assumed. Of course,
pushing `finish frame' consumes additional control frame.
Moreover, recent processors has good branch prediction,
with which we can ignore such trivial checking.
After this commit:
Finally, I decide to remove `finish frame' and `finish'
instruction. Some parts of VM depend on `finish frame',
so the new frame flag VM_FRAME_FLAG_FINISH is introduced.
If this frame should escape from VM function loop, then
the result of VM_FRAME_TYPE_FINISH_P(cfp) is true.
`leave' instruction checks this flag every time.
I measured performance on it. However on my environments,
it improves some benchmarks and slows some benchmarks down.
Maybe it is because of C compiler optimization parameters.
I'll re-visit here if this cause problems.
* insns.def (leave, finish): remove finish instruction.
* vm.c, vm_eval.c, vm_exec.c, vm_backtrace.c, vm_dump.c:

dfp (dynamic frame pointer) to ep (environment pointer).
This change make VM `normal' (similar to other interpreters).
Before this commit:
Each frame has two env pointers lfp and dfp. lfp points
local environment which is method/class/toplevel frame.
lfp[0] is block pointer.
dfp is block local frame. dfp[0] points previous (parent)
environment pointer.
lfp == dfp when frame is method/class/toplevel.
You can get lfp from dfp by traversing previous environment
pointers.
After this commit:
Each frame has only `ep' to point respective enviornoment.
If there is parent environment, then ep[0] points parent
envioenment (as dfp). If there are no more environment,
then ep[0] points block pointer (as lfp). We call such ep
as `LEP' (local EP). We add some macros to get LEP and to
detect LEP or not.
In short, we replace dfp and lfp with ep and LEP.
rb_block_t and rb_binding_t member `lfp' and `dfp' are removed
and member `ep' is added.
rename rb_thread_t's member `local_lfp' and `local_svar' to
`root_lep' and `root_svar'.

Backtrace information contains an array consists of location
information for each frames by string.
RubyVM::Backtrace object is lightweight backtrace information,
which contains complete information to generate traditional style
backtrace (an array of strings) with faster generation.
If someone accesses to backtrace information via
Exception#backtrace, then convert a RubyVM::Backtrace object to
traditonal style backtrace.
This change causes incompatibility on marshal dumpped binary
of Exception. If you have any trouble on it, please tell us
before Ruby 2.0 release.
Note that RubyVM::Backtrace object should not expose Ruby level.
* error.c, eval.c, vm_eval.c: ditto.
* internal.h: ditto.
* eval_error.c: fix to skip "set_backtrace" method invocation in
creating an exception object if it call a normal set_backtrace
method (defined by core).
* test/ruby/test_settracefunc.rb: fix for above change.
* vm_method.c (rb_method_defined_by): added. This function
checks that the given object responds with the given method
by the given cfunc.
* benchmark/bm_vm2_raise1.rb, benchmark/bm_vm2_raise2.rb:
add to measure exception creation speed. raise1 create
exception objects from shallow stack frame. raise2 create
exception objects from deep stack frame.

rb_location_t#filename, filepath, name and line_no was moved from
rb_iseq_t. rb_location_t#basename is a new field which is

`basename' only contains `foo'.
rb_iseq_t contains memory object of rb_location_t.
